Can you remember?

Have you already found yourself remembering a concept car that you saw on some magazine, TV show or the Internet just because of its image? While testing new engineering possibilities many concepts are remembered for their designs, style and stance.

Whether it’s because of the soft and smooth lines or the irreverence of their approach, some concepts are kept on people’s memories, never to leave them again.

This week we will be bringing you seven concept cars that may lye on your box of memories.

So, can you remember?

Mercedes-Benz Vision SLR

The Vision SLR was presented in 1999 at the International Detroit Auto Show as the study of a Gran Turismo for the 21st century. The concept car is a combination of stylistic elements of the current Formula 1 Silver Arrow and the SLR sports car from the 1950.

Its front fascia is dominated by the arrow-shaped nose, with the typical double spoilersbeing inspired on the Formula 1 racing car with which Mika Häkkinen won the 1998 world championship.

The long and extended hood, the powerful sweep of the wings and the gull-wing doors of the Vision SLR were inspired on the legendary SL models from the 1950s and their SLR racing variants, in which Juan Manuel Fangio, Rudolf Caracciola and Stirling Moss drove from one victory to the next.

Lamborghini Concept S

The Lamborghini Concept S was a study car presented in 2005 at the Geneva Motor Show and was an extreme and spectacular expression of the Lamborghini brand.

Designed by Luc Donckerwolke, the Concept S main feature was its 'saute-vent' (French for 'change wind') instead of a traditional windscreen. This characteristic divided the interior into two distinct compartments by continuing the bodywork between the seats. This feature served as an air inlet feeding the mid-mounted 5L V10 engine and also to give the car a distinctly futuristic look. There was also an electronically operated rearview mirror which is mounted in the middle of the two cockpits.

Mazda Furai

The Mazda Furai was a concept car presented in 2008 at the North American International Auto Show in Detroit.

Meaning “sound of the wind”, the Furai concept car was the fifth and last of the Mazda Nagare line of concept cars developed by Mazda since 2006.

The chassis featured on the Furai was based on the Courage Compétition C65 Le Mans Prototype that Mazda last used to compete in the American Le Mans Series, two seasons previously.

Designed to use E100 ethanol fuel, the Furai is powered by a 3-rotor wankel engine that boosted 450 horsepower.

Audi Avus Quattro

The Audi Avus quattro was a "supercar-styled" concept car that had its world premiere at the 1991 Tokyo Motor Show.

The Avus quattro was a futuristic sports car study with aluminium body and W12 mid-engine, proving Audi's commitment to perfect aluminium lightweight technology.

The car featured a 6 liter W-12 engine (with 3 banks of 4 cylinders) and 5 valves per cylinder. Output was 509 bhp at 5800 rpm, and 398 lb-ft at 4000 rpm. The body was finished in unpainted aluminum. Estimated top speed was 211 mph, with 0-60 appearing in an incredible 2.9 seconds.

Renault Nepta

Although when it was presented in Paris in 2006 everyone knew it wasn’t a car to go into production, the Renault Nepta was still a “show stopper” for its design.

More important than the car itself, the Nepta was important as it gave everyone a hint of the future design language of Renault. Some design elements of the Nepta such as the concave body surface, the front end styling and the long rear lights can now be spotted in some of the French brand’s models.

One of the highlights of this concept car was the huge gullwing doors that open to reveal not only the interior but the engine bay also.
